Allright- here it is.
The Japanese lost without a massive US contribution. The US built a Flying Tiger tactical bomber turn 4, and the Chinese Nationalists managed to keep the Burma Road open for a turn, so it got to Szechwan. The Russian Far East Army was in Novrosibirsik and Samara by turn 5, so the Japanese made the critical mistake of attacking Amur. This enabled the Russians to divert their tactical bomber from Moscow, and fly it to Suiyuan. The Mongolians walked into the Chinese Communist army over the next few turns, and by turn 8, the CCP had:
8 infantry, 2 of which were Mongolian
2 artillery
1 Russian tactical bomber
The Nationalists had traded Yunnan back and forth four times over the course of the game, and had lost Kwiechow, Anhwe, Hopei, and Hunan. Other than that, they were doing OK, as Szechwan was safe.
The game ended with a narrow Allied victory on turn 12. The FEC had attacked the Japanese unprovoked on turn 2, and by turn 5 had French Indo-China bulked up heavily, with
5 infantry
3 artillery
2 fighters
1 tactical bomber
mIC
Over the next three turns, they built 3 tanks a turn (they controlled Siam and Sumatra).
This forced the Japanese to build an IC in Shanghai, and built 3 tanks every turn to keep the Chinese coast safe from either the Nationalists or the FEC. This means that, out of 55 IPCs a turn, they were automatically spending 18 a turn in an arms race where the Chinese were a factor as well. Then, on turn 8, everything cracked. The CCP retook Chahar at the cost of 4 infantry, and received a Russian tank.
The Nationalist Chinese, who had been playing fairly conservatively, hit Yunnan hard with
9 infantry
6 artillery
1 fighter
1 tactical bomber.
They came out of this battle with 3 infantry dead. Finally, the FEC followed up on this with throwing everything they had at Kwangsi. This triple blow wasn’t something the Japanese could immediately counterattack. They started a new line of defence encompassing Jehol, Shantung, Manchuria, and Kiangsu. They also shipped 6 infantry to hold Hong Kong. It wasn’t enough. The Chinese Communists and Japanese wiped each other out in Jehol, while the Nationalists retook Kwiechow, Hunan, and Kiangsi without any difficulties. ANZAC was cooperative enough to eliminate the possible landing spot of Formosa.
While all of this was going on, the US was focussed chiefly in Europe, where they had done Torch and taken Rome (and were putting its IC to good use!) Normandy had been traded back and forth a few times as well. This had the effect of forcing the Germans to keep 6 infantry in Northern Italy, 2 in Albania, 4 in Yugoslavia, and 1 in Greece. They also had to keep a garrison in Paris, including a fighter to help ward of bombing. This had the effect of the Germans not being able to take Moscow, so there was no immediate danger in Europe. Therefore, the US decided that the time was right to hit the Japanese. On turn 9, they built 3 destroyers, 2 cruisers, and 2 strat. bombers. On turn 10, this all sailed out to Hawaii, as 4 loaded transports came out of WUS. On turn 12, the Japanese (who were down to 12 IPCs a turn, thanks to the Chinese mopping up the northeast, and ANZAC clearing the DEI), succumbed to a US invasion fleet. That same turn, the British captured Paris and Northern Italy, causing Germany to surrender.
Not all of this was caused directly by a stronger China, but that did influence it. Since China could do more, the Japanese did not gain easy access to the 12 IPCs of the Chinese interior, and only ever captured 6 Chinese territories over the course of the game. And holding these territories was trickier as well, as the Chinese could hit harder. Attacking Russia was a really stupid move on Japan’s part, as it not only opened up a supply route to the Communists (Mongolia), but diverted troops away from India and China. Since Japan had more on its hands, the US could focus more on Europe, contributing to Italy’s early fall and Germany’s inability to take Moscow (although strong Russian play and die-rolls played a part in the latter). Once both Axis powers were under a lot of pressure, the US could simply take Tokyo, thanks in part to good FEC play, but also because China could reconquer the valuable coast, depriving Japan of income. And once Tokyo fell, the German player knew that there was a 0% chance of taking Moscow, Paris, Rome, and Cairo. The Allied advantage in the Pacific was due partially to good FEC play and die-rolls, and the insane decision to attack Russia, but a stronger China also played a part.
Just for the record, the players were divided up into US/Nat China/France, USSR/CCP, UK/FEC/ANZAC, Japan, and Germany/Italy.
